AION 2 Mouse Sensitivity and DPI Settings

AION 2 mouse sensitivity is set almost entirely outside the game. The last first-hand look at the settings screen — SPACE4GAMES playing the September 17-18 Launch Scale Test — found eight tabs of options and no mouse sensitivity slider at all, and named the horizontal and vertical camera movement speed sliders under Graphics > Camera / Direction as the closest controls available. No source since has reported a dedicated sensitivity slider or an in-game DPI option in the global client, so the honest build of this page starts from Windows and works inward: pointer speed 6/6, Enhance pointer precision off, a DPI you can hold steady, then the two camera sliders as your fine adjustment. Every in-game value below is marked for what it is, because a test-build observation is not a launch guarantee.

What AION 2 mouse sensitivity controls actually exist

Two sources independently place the camera sliders at the same spot, which is the strongest thing this page can say. SPACE4GAMES puts them under Graphics > Camera / Direction, alongside camera distance, camera shake and the teleport effect colour, and says explicitly that it did not have time to determine whether those sliders fully solve the oversensitive mouse it felt during the test. A launch-day walkthrough reaches the same two controls through the quick-access camera icon on the left edge of the screen, just above the emote icon — hold Alt to bring the cursor up if the HUD is covering it — and calls them Camera Horizontal/Vertical Movement Speed, describing them as the same thing as mouse sensitivity. A third guide lists recommended values of 50 for both sliders in its Low and Recommended presets; treat that as one guide’s preset rather than a documented default, and label it unverified in global.

How to check what your own client offers: open the camera icon, then drag each Movement Speed slider to both ends. The minimum and maximum are not documented anywhere public, and dragging is the only reliable way to learn them. If your build has a dedicated sensitivity slider, it supersedes everything on this page — note the date you found it, because it is exactly the change SPACE4GAMES said it would document.

Set Windows pointer speed to 6/6 and turn off Enhance pointer precision

This step is cheap, reversible, and it is what makes the DPI numbers in the next section mean anything. It applies to Windows 10 and Windows 11, and the path differs slightly between them: Windows 11 goes to Settings > Bluetooth & devices > Mouse, then Related settings > Additional mouse settings. Windows 10 goes to Settings > Devices > Mouse, then Related settings > Additional mouse options. Both land on the same Mouse Properties > Pointer Options tab, which Control Panel > Mouse reaches directly on either version.

On that tab, do two things:

• Set pointer speed to 6 of 6. Not a guess — 6/6 with acceleration off is the conventional raw-input baseline, the point at which a DPI number describes the same physical distance on every machine.
• Uncheck Enhance pointer precision. That checkbox is Windows’ built-in acceleration curve. Left on, small movements get scaled down and fast movements get scaled up, which makes a camera feel inconsistent at exactly the moment you are tracking a target.

Why it matters depends on how the client reads the mouse, and that is the one thing nobody has confirmed. The general Windows rule: an application reading standard pointer messages is affected by the pointer-speed slider and by Enhance pointer precision, while an application reading raw input bypasses both. So if AION 2 ignores the pointer-speed slider in game, the 6/6 step is harmless but your DPI-to-camera ratio is no longer 1:1 — which is exactly what the next section has to account for. If you are picking up the client fresh, the PC system requirements page covers what the machine needs beyond input settings, and the controller support page covers the other input path.

Raw input: the ten-second test

Nobody has confirmed whether AION 2 uses raw input, and you can check it faster than you can find an answer. Pick a fixed physical distance — the width of your desk mat is fine. Move the mouse exactly that far while watching the camera, then change the Windows pointer-speed slider and repeat.

• The view moves the same amount regardless of the slider. The client is not using OS pointer scaling, which is raw-input behaviour. Your DPI table below now describes real screen-centimetres per turn.
• The view changes when the slider moves. The client reads standard pointer input. Use the DPI table as a relative starting point — it still ranks your options correctly — and let the camera sliders do the rest.

Either result is useful. What is not useful is tuning DPI on a machine with Enhance pointer precision still enabled and then concluding the game ignores your settings.

DPI and cm/360: the numbers to start from

There is no documented in-game DPI option for AION 2, so DPI lives in your mouse software and the camera sliders do the rest. With pointer speed at 6/6 and acceleration off, and assuming a 1:1 read, the arithmetic is simple: a mouse reports 36000 counts per inch, so a full turn of 360 degrees is 36000 × 2.54 = 91440 centimetres divided by your DPI.

Two caveats sit on that table. It holds only if the read is 1:1 — if the client applies its own multiplier or scales the camera against pointer speed, every figure shifts by that multiplier. And the physical distance per turn is only worth tuning if you can keep it: a sensitivity you have to correct constantly costs more than the turn distance saves. Start at a DPI your mouse can hold without drifting, set both camera sliders equal, and adjust from there. You do not need to match anyone else’s number, and if you want a comparable baseline across machines, that is what the table is for. The gameplay overview covers what the combat actually asks of your hands, and the macro guide covers the other half of input setup.

Two monitors: DPI is one device setting, not two

You cannot set a separate mouse DPI per monitor in Windows. Mouse DPI is a single property of the device, set in the mouse’s own software, and Windows has no built-in per-monitor pointer speed control. What actually differs between a 1080p and a 4K panel is display scaling and whether the application is per-monitor DPI aware — and AION 2 is not verified in global on the second point.

So the practical approach is: keep one DPI, and treat a per-monitor difference as something to correct rather than something to configure away. Check the scale in Settings > System > Display for each panel, then test camera travel on both. If one screen turns noticeably faster, and you have the option, Properties > Compatibility > High DPI scaling override tells you how the client is being scaled; and where the client offers separate horizontal and vertical camera speeds, those are your per-screen correction — nudge them rather than rebuilding your whole setup.

Windowed mode and mouse capture

If your camera stops responding when the cursor reaches the screen edge, that is a capture problem, not a sensitivity one. The display mode lives under Settings > Graphics > Optimize > Display Mode, which secondary guides list as Borderless Window Mode, Full Screen Mode and Windowed Mode — and switching away from Borderless Window Mode is what unlocks the Resolution dropdown in the same tab. Labelled reported and not verified in global, since the launch-day patch notes covered the Key Settings menu list rather than display modes.

Try the modes in order — full screen first, then borderless — and restart between each, because a display change in an MMO often only applies on a fresh client. If the cursor still escapes while you are turning, that is where the general Windows and Steam workaround for capture problems applies: Steam’s per-app launch option to disable fullscreen optimizations. It is general practice rather than an AION 2 fix, and it is worth knowing that a player in the Advance Access thread blamed the Steam overlay for a related symptom — the camera stopping dead rather than drifting. Close the overlay and re-test before you start changing settings. The global versus KR/TW page explains why a settings answer from the Korean and Taiwanese build may not match what you see, and the server status page covers what happened around the October 5 release.

Evidence level: system documentation for the Windows steps and the cm/360 arithmetic; first-hand observation for the absence of a sensitivity slider in the Scale Test build; secondary guides for every menu path and in-game value, all labelled unverified for the global client. The cm/360 table is arithmetic from 36000 counts per inch and holds only under a 1:1 read, which the raw input test above is designed to establish. No slider range, no in-game DPI option and no in-game default has been invented for this page; where a value exists only in one guide’s preset, it says so.
